A controller does not control a request for location registration with respect to the base station even though the user of the mobile radio telephone moves between registered location areas when the inhibition request is stored in the first memory.
Description
The present invention relates to mobile radiotelephone, the location registers that is used for mobile radiotelephone is more specifically forbidden control device and method thereof.
Under the situation that mobile radiotelephone (hereinafter being called " phone ") user moves in comprising the location registers zone scope of predetermined a plurality of service areas, location registers is carried out in this phone request base station, sends the required time cycle of signal so that reduce from the base station to phone.When the position register request that receives from this phone, control station executing location registration of this base station requests.This control station response is stored in the positional information storage sites current location of this phone from the request of this base station.
In this location registers,, can cause phone between a plurality of service areas, frequently to move as telephone subscriber by bus or during the similar tool high-speed mobile.The result is, the frequency of phone location registration increases, and the problem of the control operation burden of the control station relevant with location registers occurred increasing the weight of.
In order to address the above problem, for example, on May 25th, 1993, disclosed Japanese Patent Laid was open, had disclosed a kind of known location registration system among the flat 5-130019.
This location registration system is like this design, makes phone detect the signal quality of received signals, and when this degraded signal quality, judges that then this telephone subscriber is with high-speed mobile.Judge this phone under the situation with high-speed mobile at it, for example, even this telephone subscriber moves in a location registers zone scope, this system forbids from the position register request of phone to a base station.
By the way, in the mobile radio telephone system that Japan uses, the Sending dialled number number that is used for called telephone between short distance calling and the long distance call is distinguishing.This is because control station charges equably to the calling party (hereinafter referred to as " calling party ") of called telephone.For example, when the short distance that is equal to or less than 160km was called out, calling party dialled 030, and when the long distance call of carrying out greater than 160km, calling party dials 040.
Control station calculates distance between calling party and the called phone according to called phone position registration zone, and judges that the calling from this calling party is that long distance call or short distance are called out.Do not consider should dial under the situation of " 030 " calling out by the fact of long distance call from the calling of calling party in calling party, this control station is with the message informing calling party of " please redial " 040 " ".Otherwise, not consider should dial under the situation of " 040 " calling out by the fact that short distance is called out in calling party from the calling of calling party, this control station is with the message informing calling party of " please redial " 030 " ".
Therefore, when the calling party called telephone, the user do not consider to make an appointment calling party he be in and can dial this fact of position that call out " 030 " that short distance calls out, do not dial under 040 situation about can not call out the message of this control station notice " please redial " 040 " " and move to.Cause this notifications calling party like this, the telephone subscriber has been interrupted the defective of the agreement of itself and calling party.
For solving this defective, can turn off telephone power.Yet, in this case, because the message informing calling party that this control station will " telephone power be switched off ", therefore exist calling party and infer that this telephone subscriber interrupted the possibility that itself and calling party are arranged.
In view of the foregoing made the present invention, therefore an object of the present invention is to provide the location registers that is used for mobile radiotelephone (hereinafter being called " phone ") forbids control device and method thereof, can prevent to notify to calling party telephone subscriber's current location.
Another object of the present invention provides a kind of control device and method thereof, so that the telephone subscriber selects to forbid or allow location registers arbitrarily.
For achieving the above object,, provide a location registers to forbid control device according to the present invention, comprising: a location registers inhibition request key is used to ask location registers to forbid; With an inhibit circuit, be used for when location registers inhibition request key request location registers is forbidden, even this user leaves a location registers zone, forbid carrying out location registers with respect to a base station.
In addition,, provide a kind of location registers to forbid control method, comprising step: detect the band of position that the mobile radiotelephone user has left registration according to the present invention; Detecting the request location registers forbids; With forbid carrying out location registers.
By said apparatus, in the present invention, the telephone subscriber can disabled position register the current location of asking and preventing to notify to calling party the telephone subscriber.Therefore, the telephone subscriber do not consider to make an appointment calling party he be under the situation of possibility that the fact of calling out the position that can call out by short distance moves to the position that can not call out by long distance call, for preventing to notify this user to interrupt the agreement of itself and calling party to calling party, this user operating position registration in advance inhibit circuit is so that it can ask location registers in phone.
In these cases, even the telephone subscriber calls out between the zone that the zone that can not call out and non-long distance call can not call out in non-short distance and moves, because this phone does not carry out location registers with respect to control station, control station can not be grasped this phone position.So, in this case, though this calling party called telephone, control station notice " " this class message that a called phone is shifting out the coverage at present.When weak wireless signal caused a call failure, this class notice appearred in the routine call system.That is, carry out this notice continually.Therefore, calling party can not judge above-mentioned notice be cause by call failure or ask location registers to forbid causing by the user, and can not judge that this user interrupted the agreement of itself and calling party.

Next with reference to figure 5 (a), 5 (b), 6 (a) and 6 (b) down control channel is described.
Among Fig. 5 (a), a superframe is made up of 0 to 17 frame, and its length is 720ms.
Among Fig. 5 (b), in the structure of time slot of half rate, every frame is made up of time slot ST# 0 to 5.Time slot ST# 0 to 2 or time slot ST# 3 to 5 comprise a subframe, and the length of each subframe is 20ms.
Among Fig. 6 (a) and 6 (b),, be assigned with one of any among BCCH, a single mesh signaling channel of special use (SCCH) and the PCH respectively for ST# 0 that comprises a sub-frame preamble time slot or ST# 3.
BCCH comprises PCH information, and one judges whether carry out the predetermined level of location registers and the region code in a location registers zone, comprises the base station that sends present received control channel signals in this location registers zone.SCCH also is assigned to the uplink and downlink control channel, and is used when a calling is connected to the base station.When receiving a calling, comprise the telephone number of a phone among the PCH.
Then, under control, be pulled to the phone operation that radio-circuit 102 begins the discontinuous operation processes with reference to figure 7 (a), 7 (b) and 8 descriptions from power supply.
Among Fig. 8, when power supply is switched under control (step S1), controller 103 makes radio-circuit 102 these operations of response connect (step S2).After the connection, radio-circuit 102 begins to scan a plurality of predetermined receive frequencies, so that set the carrier frequency (step S3) that is received in down control channel.Radio-circuit 102 finish scanning all a plurality of predetermined receive frequencies after (step S4), controller 103 is according to the electric field strength of the channel signal of each receive frequency that can pass through this scan operation acquisition, the receive frequency of radio-circuit 102 is set at the frequency of the control channel signals that is detected highfield intensity, (step S5).
Radio-circuit 102 beginnings receive the down control channel carrier wave at a receive frequency that sets, and receive the BCCH (step S6) that is comprised in the predetermined time slot.
In this situation, in Fig. 7 (a) and 7 (b), after the receive frequency of having set radio-circuit 102, radio-circuit 102 is at moment t1 receiving slot ST#5.Radio-circuit 102 continues to connect, and receives a predetermined time slot that is assigned with BCCH up to it, and at power supply after time slot ST# 0 connects, at first receive BCCH at moment t2.
Come back to Fig. 8, when radio-circuit 102 has received BCCH (step S6), controller 103 comprises the base station that sends the control channel signals with present received frequency from the region code of the restituted signal detection position registration zone of BCCH in this location registers zone.Then, controller 103 makes second memory 108 that region code is stored in wherein, and determines the PCH (step S7) of this phone from restituted signal.Determine after the PCH of phone that radio-circuit 102 begins to carry out discontinuous operation, so that only receive (step S8) at the time slot that is assigned with BCCH or PCH in advance.
Below with reference to Fig. 7 (a) and 7 (b) this operation is described.
Radio-circuit 102 is determined the PCH of this phone when moment t2 receives BCCH.Then, radio-circuit 102 is turned off, up to the time slot ST# 0 that has been assigned with phone PCH in its reception of moment t3.When moment t3 received PCH, radio-circuit 102 was turned off once more and keeps turn-offing at moment t4, up to the time slot ST# 0 that is assigned with BCCH in its reception of moment t5.When moment t5 received BCCH, radio-circuit 102 was turn-offed once more at moment t6.After this, repeat identical intermittence and receive operation.
Next will location registering method be described with reference to figure 9.
Among Fig. 9, intermittently receiving operating period, when radio-circuit 102 receives BCCH (step S9), controller 103 detects the electric field strength of the control channel signals that receives and reads predetermined level from the restituted signal of BCCH, so that it judges whether the electric field strength that detects is not higher than this predetermined level (step S10).This is higher than in electric field strength under the situation of predetermined level in judging, radio-circuit 102 carries out receiving operation the intermittence identical with the operation of front and turning back to step S9, so that receive the BCCH that sends here subsequently.
On the other hand, be not higher than in electric field strength under the situation of predetermined level, controller 103 judges whether the location registers disable code has been stored in (step S11) in the first memory 107.Under the location registers disable code had been stored in situation in the first memory 107, controller 103 was not controlled the position register request from this phone to this base station.
On the other hand, under the location registers disable code was not stored in situation in the first memory 107 yet, radio-circuit 102 began to scan a plurality of predetermined receive frequencies (step S12).Radio-circuit 102 has scanned (step S13) after all these a plurality of predetermined receive frequencies, controller 103 is according to the electric field strength of the control channel of each receive frequency that can obtain by this scan operation, the receive frequency of radio-circuit 102 is set at the frequency (step S14) of the control channel signals that is detected highfield intensity.
Radio-circuit 102 beginnings receive the down control channel carrier wave at the receive frequency that sets, and receive the BCCH (step S15) that is comprised in the predetermined time slot.Controller 103 comprises the base station that sends the control channel carrier wave with present received frequency from the region code of the BCCH restituted signal detection position registration zone of reception in this location registers zone.Then, radio-circuit 102 is stored in the region code in the location registers zone detected in the second memory 108 and up to the region code in the location registers zone of the base station of the control channel carrier wave of present received frequency relatively (step S16) with wherein comprising to send to have.As this comparative result, when the former was identical with the latter, controller 103 was not controlled the position register request from this phone to this base station.
On the other hand, when the former and the latter not simultaneously, controller 103 writes the region code of storage in the second memory 108 again at present detected region code (step S17) and sends position register request (step S18) to the base station.When this request of controller 103 response, when receiving by radio-circuit 102 from affirmation request that this base station sends (step S19), this controller 103 sends confirms response (step S20).This request of controller 103 responses receives the location registers that sends from this base station by radio-circuit 102 and receives (step S21), thereby finishes the position register request control from the phone to the base station.
As mentioned above, the present invention can forbid position register request from phone by the user.Therefore, exist the telephone subscriber not consider this user calling party of making an appointment, he is positioned at the fact that can call out by the short distance calling and moves under the situation of the regional possibility of long distance call, be the agreement that prevents to notify this user to interrupt itself and calling party, disabled position registration request before the user moves to long distance call zone to calling party.
In these cases, when the user moved to long distance call zone, because this phone does not carry out location registers, control station can not be grasped this phone position, and can not make the current location of storage mobile radio station in the positional information storage sites 5.So, in this case, when the calling party called telephone, the message of control station notice " called phone shifts out the coverage at present ".
When call failure occurring, produce this class notice in the routine call.Be that this notice often produces.Therefore, calling party can not judge that above-mentioned notice is that the fact by phone disabled position registration or call failure causes, and this calling party can not judge that the telephone subscriber interrupted the agreement of itself and calling party.
Among this embodiment, controller 103 judges whether the electric field strength of the control channel carrier wave with receive frequency is not higher than (the step S10 among Fig. 9) after the predetermined level, controller 103 judges whether the location registers disable code has been stored in (the step S11 among Fig. 9) in the first memory 107, thereby judges and to forbid or allow location registers.Yet the judgement that location registers is forbidden is not limited to the step after conduct meets step S10, if this judgement was carried out before controller 103 sends position register request, can carry out any step (the step S18 among Fig. 9).
Next given another embodiment of the present invention will be described.
In this embodiment, even first memory 107 comprises the memory of also memory contents not being wiped when a power supply 106 is turned off.If when power supply was switched under control, the location registers disable code had been stored in the first memory 107, controller 103 is not to controlling to the position register request of base station from phone.
By said structure, even moving to, the telephone subscriber do not dial the position that " 040 " can not call out, in control power down source, ShiShimonoseki 106, energized 106 under control then, because position register request is under an embargo, control station can not be grasped the position of this phone.
Among this embodiment, RCR STD-27B is as a case description of phone standard, yet the present invention is not limited to this class standard.
In addition, the foregoing description is described by portable phone, yet the present invention can be applicable to automobile telephone or similar device equally.
As mentioned above, according to the present invention, consequently request is from the location registers of phone because keyboard portion 104 is made into this structure, and the telephone subscriber can select to forbid or allow location registers.
Therefore, exist the telephone subscriber do not consider this user make an appointment calling party he be in the fact in the short distance calling area and move under the situation of possibility in long distance call zone, the telephone subscriber can the disabled position registration.
Clearly, can make many other improvement and variation to the present invention by above-mentioned instruction.Therefore, should be appreciated that in the appended claims scope, can do specifically describing the outer the present invention of enforcement here.
